Report not generating in case of minimal, expansive and intensive

[SinghSensai]

Help me understand this, if the stream_research2_events function ends at

yield make_message(
            {
                "type": "completed",
                "description": "Research completed",
            },
            session_key,
        )

How can we generate report. And where can I add my custom function which i want to use in place of tavily for searches(for these three strategies)
